PETER THEOBALD, OF OARRIGK, PENNSYLVANIA.

AUGER-HOLDER.

SPECIFICATION forming part of Letters Patent No. 689,434, dated December24, 1901.

Application filed April 11, 1901. Serial No. 55,296. (No model.) I

To all whom it may concern.-

Be it known that LPETER THEOBALD,a citizen of the United States ofAmerica, residing at Carrick, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inAuger- Holders; and I do hereby declare the following to be a full,clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in devicesfor holding angers while sharpening same, and has for its object toprovide new and efiective means whereby an anger may be securely helddur-' ing the operation of repoin ting or sharpening the same.

The invention is particularly adapted for use in places where the viseor like device cannot be obtained for holding the auger.

In the accompanying drawings, Figure 1 is a side elevation of the deviceready to receive an anger. Fig. 2 is a side elevation showing the augerheld therein. Fig. 3 is a top plan view of the same. Fig. 4 is atransverse Vertical sectional view. Fig. 5 is adetail perspective viewof the crank by means of which the device is tightened and also by meansof which the pivoted jaw is operated to clamp the auger. Fig. 6 is adetail, perspective view of the adjustable sleeve carried by thesupporting-bolt. Fig. 7 is a detail perspective view of a part of thesupporting-bolt.

It is the object of my invention to provide a device which may beattached to a suitable supporting-post, and in the accompanying drawings1 indicates such a support around which is passed a chain 2, said chainbeing connected to hooks 3, carried by the collar 4,

which is threaded on the shaft or bolt 5, provided at its free end witha head 6. Mounted on this bolt or shaft 5 is an adjustable sleeve 7,provided on its upper and lower faces at the forward end with cut-awayportions 8 and at its rear end with like cut-away portions 9. A crank 10is provided with a head 11, which is threaded on said bolt 0r shaft 5.The collar 4carries a downwardlyextending arm 12, forming one jaw of thevise, which holds the auger 14, and the other jaw 15 being pivoted tothe lower end of the rigid jaw 12, with its free end concaved, as shownin dotted lines in Fig. 4, so as to partially straddle the shaft or bolt5.and permit the operation of the pivoted jaw.

In operation the bolt is placed with its threaded end against the faceof the supporting-post 1, the chain having either its link at one end orthe link near one end engaged with one of the hooks 3, and the chain isthen passed around the post and connected to the other hook 3, as shownin Fig. 3. The crank 10 is rotated upon the bolt or shaft 5 toward theheaded end of the bolt or shaft until the head 11 of said crank isengaged within the cut-away portions 9 of the sleeve 7, the cut-awayportion 8 of said sleeve receiving the head 6 of said bolt. thisposition and the crank 10 is operated, it will be held rigid with thebolt or shaft 5, and as the latter is rotated within the sleeve 4 thechain will be tightened, so as to hold the device in the supportingposition, as shown in Figs. 1, 2, 3, and 4. The crank 10 is then againengaged with the threaded portion of the bolt or shaft 5 and is rotatedu ntil brought into engagement with the pivoted jaw 15, near the upperend thereof, forcing said jaw toward the rigid jaw 12 and securelyclamping the auger 14 between said jaws.

It will be observed that as the head 11 of the crank passes out ofengagement with the threads of the bolt orshaft 5 the crank may bereadily slipped into the cut-away portions 9 of the sleeve, so as totighten the shaft or bolt 5 against the supporting-post, as heretoforedescribed.

It will be noted that various changes may be made in the details ofconstruction without departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a clamping device for the purpose specified, the combination witha threaded bolt or shaft having a head on one'end, of a collar threadedon said shaft and provided with hooks to receive the securing-chain, arigid jaw carried by said collar, a pivoted jaw WVhen in.

carried by the rigid jaw, a crank mounted on the head of the bolt andthe head of the crank whereby the crank and bolt or shaft may be rotatedin unison, as and for the purpose described.

2. In a clamping device for the purpose described, the combination witha support, of a threaded shaft or belt, a collar threaded on said shaftand carrying hooks, a chain connected to said hooks and support, a rigidjaw carried by the collar, a pivoted jaw connected to the rigid jaw, acrank threaded on the belt or shaft, and means for securing said crankto the bolt or shaft whereby they may be retated in unison,substantially as described.

3. In a device of the character described,

the combination with'a support, of a belt or PETER THEOBALD.
